CALCulate<Ch>:PARameter:SDEFine
CALCulate<Ch>:PARameter:SDEFine:SENDed
S<out><in>
Selects one of the four elements of the standard 2-port S-parameters as a measured
quantity for the active trace.
Remote command:
CALCulate<Ch>:PARameter:MEASure "<Trace_Name>", "S11" | "S12" |
"S21" | "S22"
CALCulate<Ch>:PARameter:SDEFine "<Trace_Name>", "S11" | "S12" |
"S21" | "S22"

With the active logical ports distributed to m DUTs with n

ports, respectively, the
analyzer creates n

diagrams and displays the full set of S-Parameters, one
in each diagram. The diagrams are arranged as an n x n grid.
If "All S-Params" would result in more than 100 diagrams being created, a warning dia-
log is opened that lets you cancel the diagram creation.
The reflection coefficients S
ii
appear in the diagrams on the main diagonal, the trans-
mission coefficients S
ij
(i ≠ j) occupy the other diagrams. By default, reflection coeffi-
cients are displayed in Smith diagrams; transmission coefficients in Cartesian dia-
grams "dB Mag" scale.

S-Param Wizard...
Opens a dialog that guides you through the setup of a standard multi-port S-parameter
measurement in a frequency sweep. See Chapter 6.2.1.2, "S-Parameter Wizard",
on page 260.
Dialog and opener button are not available for R&S ZNBT, or if a switch matrix is con-
figured.
Balanced Ports...
Opens a dialog that allows you to enable/disable physical ports and to define logical
ports (balanced or unbalanced) in the active channel. See Chapter 6.2.1.3, "Balanced
Ports Dialog", on page 262.
Note: If either multiple DUTs are configured (see Chapter 6.12.2.3, "Define Parallel
Measurement Dialog", on page 535) or the "Fixture Simulator" is disabled for the rela-
